原句有误,应为
What's the weather like today?
或
How's the weather today?
今天天气如何?
答:It's sunny/rainy/cloudy. 晴天/雨天/阴天。
两句为同义句,What引导需用like,How则不需。
What's the weather today?今天天气怎么样?
回答:
It's rainy(下雨)/cloudy(刮风)
sunny(天晴)/snowy(下雪)
today
等等
得看情况。晴朗就it's sunny. 下雨就it's rainy.多云就it's cloudy.雾就it's forggy
It's rainy/snowy(形容天气的形容词)
It's....(加天气如sunny)
